Three-Stage Treatment of Transcalcaneal Talonavicular Fracture Dislocation; A Case Report and Literature Review

Transcalcaneal talonavicular fracture dislocation is an extremely rare debilitating injury with high complication rates. The present case report demonstrates highly comminuted joint-depressed fracture of left calcaneus treated with primary subtalar arthrodesis following reduction and fixation of the calcaneus. The right ankle sustained a highly comminuted fracture of calcaneal body with completely-destroyed posterior facet, fracture dislocation of the calcaneocuboid joint, dorsally dislocated talonavicular joint, fracture of anterior of tibial plafond, and subluxation of the tibiotalar joint. At first, talonavicular joint was reduced and fixed using a plate followed by reduction of calcaneus and arthrodesis of subtalar and calcaneocuboid joints. The plate of talonavicular joint was removed after 70 days. Logical approach to this injury can lead to an acceptable function.
